It would seem

options dtrace
options dtraceall

are incompatible with

options zfs

This is on base/head, r365358, amd64.

Automatic reboot in 15 seconds - press a key on the console to abort

I don't mind having dtraceall_load="YES" in /boot/loader.conf; I have

Can this latter .ko file be made part of the kernel using an option
